Closing
Follow the instructions below to ensure that the heat exchanger will be pro perly closed.
For bolt identification, refer to “Bolt configuration” on page 20.
Step 1
Check that all the sealing surfac es are clean.
Step 2
Brush the threads of the bolts clean, using a steel wire brush or
the Alfa Laval thread cleaner. Lubricate the threads with a thin
la yer of grea se, e.g. Gleitmo 800 or its equivalent.
Step 3
Attach the gaskets to the plat es or check that all gaskets
are properly attached. Check that all gaskets are correct
ly
positioned in the grooves.
Note!

fact that it rises out of th e gasket gr oove or that it is
positioned outside the groo ve.
Step 4
If the plates have been removed, insert them in alternate
di rections and with the gaskets turned towards the frame plate
or pressure plat e as specified on the plate hanging list. Use
the marked line that was m ade when the heat exchanger was
opened, refer to Step 7 in “Opening” on page 20.
Step 5
If the plate pack has been marked on the outside, check t his
(s ee Step 7 in “Opening” on page 20).
If the plates are corre ctly assembled (A/B/A/B etc.), the edges
form a “honeycomb” pattern, see picture.
